The first Earth Day on April 22, 1970, activated 20 million Americans from all walks of life and is widely credited with launching the modern environmental movement. The passage of the landmark Clean Air Act, Clean Water Act, Endangered Species Act and many other groundbreaking environmental laws soon followed. Growing out of the first Earth Day, Earth Day Network (EDN) works with over 22,000 partners in 192 countries to broaden, diversify and mobilize the environmental movement. More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world.
But Earth Day Network does not stop there.

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply worried about the future.

James Hansen has made key insights into our global climate and inspired a generation of activists and scientists.

“On November 11th, 11.11.11, across the planet, documentary filmmakers, students, and other inspired citizens will record the human experience over a 24-hour period and contribute their voice to the second annual global day of media creation called One Day on Earth. Together, we will create a shared archive and a film.

Founded in 2008, One Day on Earth’s first media creation event occurred on 10.10.10. The collaboration was the first ever simultaneous filming event occuring in every country of the world. It created a unique geo-tagged video archive as well as an upcoming feature film.

Together, we are showcasing the amazing diversity, conflict, tragedy, and triumph that occurs in one day. We invite you to join our international community of thousands of filmmakers, hundreds of schools, and dozens of non-profits, and contribute to this unique global mosaic. One Day on Earth is a community that not only watches, but participates.”

“What can change in a day? Everything. On September 14, the world will focus its attention on the truth about the climate crisis. For 24 hours, we will all live in reality. Pick a faraway place or a city near you. Make it yours for one day. We’re hitting every time zone — but only once. 7 p.m. in your time zone. Choose a location and get involved.

“Earth Day Network today announced a collaboration with Facebook to engage people worldwide in environmental action through the Billion Acts of Green®campaign. The two organizations worked together to create a new application or “app” that is inspiring people around the world to take actions to reduce their impact on the environment.

A Billion Acts of Green®is a global campaign that drives voluntary efforts to improve our environment. It encourages individuals and organizations to undertake acts of environmental service and advocacy, and to share them with the world. These actions can be immediate changes like switching to energy efficient light bulbs, or large-scale projects that achieve lasting change, such as efforts to green our cities and our schools.”
